EXHAUST MECHANISM.

SPECIFICATION forming part of Letters Patent No. 701,204, dated May 27,1902.

Application filed October 5, 1901.

T0 (LZL whom it may concern.-

Be it known that I, THEODORE D. KLINE, a citizen of the United States,residing at Savannah, in the county of Chatham and State of Georgia,have made certain new and useful Improvements in Exhaust Mechanism, of

.which the following is a specification.

Hy inventionis an improvement-in exhaust mechanism for use onlocomotives; and the invention consists in certain novel constructionsand combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure l is a side elevation of the exhaust mechanismembodying my invention. Fig. 2 is a longitudinal section thereof onabout the line 2 2 of Fig. 3. Fig. 3 is a longitudinal sect-ion of themechanism on about the line 3 3 of Fig. 2. Fig. 4 is a longitudinalsection similar to Fig. 3, but showing the valve adjusted to open theauxiliary exhaust-flue. Fig. 5 is a top plan view of the mechanism. Fig.6 is across-sectional view on about line 6 6 of Fig. 2. Fig. 7 is across-sectional view on about line 7 7 of Fig. 3. Fig. 8 is across-section on about line 8 o of Fig. 3, and Fig. 9 is across-sectional view on about line 9 9 of Fig. 3.

In practice the exhaust mechanism in the form of a regulator occupiesthe same position in the smoke-box of a locomotive as the ordinaryexhaust-pipe now in use, and I form the body A of the regulator by meansof a central partition A with side flues A to which the exhaust from theopposite cylinders is delivered by pipes in any suitable manner. Bypreference I form the body A of the regulator of a cylindrical casing a,which is divided longitudinally by the partition A, and such casing ispreferably tapered toward its upper end, where it delivers to theconfluent chamber B, whose upper end is in communication with the mainexhaust-flue C and the auxiliary exhaust-flue D, communication with theflue D being controlled by the valve E, which valve is arranged toopcrate in a lateral extension B of the chamber B and for adjustment, asshown in Fig. 3, to cut off the auxiliary flue D or, as shown in Fig. 4,to open the communication between the chamber B and the flue D wheneverit.is desired to give the maximum or minimum draft on the fire.

Serial No. 77,681. (No model.)

The valve E is hinged at It, so it can be turned from the position shownin Fig. 3 to that shown in Fig. 4, and vice versa, and is secured upon ashaft F, which may be provided with a crank-arm and connected with asuitable operating-lever in the cab of the engine, which may be operatedto adjust the valve to any desired position, and suitable detent devicesmaybe provided for securing the valve in any position to which it may beadjusted.

' It will be noticed from Fig. 9 that the lower portion of the body A ofthe device is circular in cross-section and from Fig. 8 that the form ofthe body of the regulator at its upper end is rectangular, which is alsothe form of the chamber B, which may be termed a confluent orintermediate chamber. It will also be noticed from Fig. 7 that thecross-section of the regulator at the lower end of the main andauxiliary exhaust-fines is rectangular, affording a square seat for theswinging edge of the valvelE, and that the upper portion of theregulator gradually assumes a circular form in cross-section, as will beunderstood from Figs. 5 and 6;

In forming the regulator I find it desirable to cast the bodyA, theexhaust-fines O and D, and the front and rear plates b and b of theintermediate chamber B in one piece, and to close the sides of thechamber B by the side plates G, which may be suitably bolted in place,as shown in Figs. 1, 2, and 5, and will operate to inclose the valve anddirect the exhaust to the fines.

In supporting the shaft F, I extend it at f at one end beyond the sideedge of the valve, so it can have'a bearing in a boss F on one of theside plates Gqthe other end of the shaft being extended through astuffing-box at f so it can be connected with the operating devices, asdesired. The side plates G are planed on their inner faces and the outeredges of the regulator are also planed to receive the said sideplate,making a steam-pipe joint when the plates G are bolted in place.In Fig. 3 I show the valve E adjusted to close the auxiliary opening orflue D, which causes all of the exhaust to pass out of the main flue O,which gives the maximum draft on the fire. This Fig. 3 also shows thechange of form of the regulator, where it gradually I the art.

It will be noticed from the drawings and the foregoing that the flues Oand D form at their upper ends concentric nozzles for the discharge ofthe exhaust-steam, the main flue 0 being centrally within the flue D atthe upperend of the latter, and the said flue D encircling the flue O atits upper end and gradually reducing toward its lower end, where itopens at dto one side of the main flue O, as shown.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In an exhaust mechanism for locomotives, the combination with a mainexhaustflue, of an auxiliary exhaust-flue opening at its lower end atone side of the main line and gradually enlarging circumferentiallyaround said main flue above its lower inlet end, and means controllingthe auxiliary flue, substantially as set forth.

2. The combination in anexhaust mechanism substantially as described, ofa main exhaust-flue, and a side exhaust-flue opening at its lower endlaterally to the main flue and gradually widening circumferentiallyabove said opening, substantially as set forth.

3. The combination of the main exhaustflue, the supplemental orauxiliary exhaustfiue arranged alongsidethe main flue and encircling thesame at its upper end and gradually reducing to an opening lateral tothe main flue at the lower end of the auxiliary flue whereby there areprovided two concentric nozzles at the upper end of the regulator and areduced auxiliary flue-opening at the lower end of the main flue, and avalve controlling the auxiliary exhaust-flue, substantially as setforth.

4. The combination in an exhaust mechanism of the main or body portion,the intermediate chamber, the exhaust-nozzles above the said chamber andin communication at their lower ends therewith, said nozzles beingcomposed of an inner or central nozzle and an outer nozzle encirclingthe inner nozzle at its upper end and gradually reducing toward itslower end and opening at said end laterally to the inner nozzle, and avalve controlling the lower end of the auxiliary nozzle,

rectangular in cross-section and extending laterally beyond thecircumference of the body portion, the main flue in line with the bodyportion, the supplemental or auxiliary flue having a circular upperportion encircling the orifice of the main flue and gradually narrowingthence toward its lower end and communicating at such end with the upperend of the lateral extension of the intermediate chamber, and the valvecontrolling the lower end of the supplemental flue, substantially as setforth.

6. An exhaust mechanism comprising the main flue, the supplemental orexhaust flue, encircling themain flue at its upper end and having aninlet-opening at its lower end and gradually converging or narrowingfrom its upper circular portion toward such inlet-opening substantiallyas set forth.
